Anyone who read last month’s stereo digital recorder round-up will be aware of the Tascam DR-1, a portable general-purpose stereo recorder that offered a few extra features that would appeal to guitarists – notably a chromatic tuner, metronome, some of the playback features found in Tascam’s range of phrase trainers and an overdub facility. The new GT-R1 takes that a stage further, building on the DR-1’s feature set with the addition of a dedicated guitar input, amp simulations and an onboard rhythm machine.
